Blade Maintenance
IMPORTANT: The mower blade is sharp and can cause severe
personal injury if handled incorrectly. Wrap the blade or wear
protective gloves, and use extra caution when handling.
The steel blade is designed to provide a fine cut in long or
tough grass. Deterioration in the quality of cut indicates blade
wear or damage.

WARNING!
An excessively vibrating lawn mower
indicates that the blade is not properly balanced or has
become deformed from striking an object. In this case, the
blade must be repaired or replaced. Please follow the proper
maintenance procedures for blade care or call the

(1-866-766-9563). The use of parts that do not meet the
original equipment specifications may lead to improper
performance of the lawn mower, may compromise operator
safety, and will void the manufacturer's warranty.
1. Disconnect the electrical supply to the lawn mower and
wait until the blade comes to a complete stop.
2. Turn the lawn mower on its side, put a block of wood
between the blade and the mower deck to prevent the
blade from turning. Loosen the blade nut by a 15 mm
wrench or socket (Fig. 16).
3. Remove the blade nut, washer, blade insulator, and the
blade (Fig. 17).
4. Make sure the rotor assembly is pushed completely
against the motor shaft. Place the new blade against the
rotor assembly. Make sure the new blade is installed with
the curved ends pointing up towards the mower deck, and
replace the blade insulation, the blade washer, and the
blade nut (Fig. 18).
NOTE: Make sure all parts are placed in the exact order same
with when they removed.
